[Q] CM 10.1 MTP Problem - LG Optimus 4X HD

Hi,
First of all: I thought I could use USB mass storage in CM 10.1 before I installed it yesterday. Now I know that it is not possible right now and I have to use the MTP option. The problem here is that it does not work correctly and I don't know what to do. When I connect the P880 to the computer using USB I can access the P880 as "portable device(s)" as usual with MTP. Then I click it and it is always empty. I copy files on it which works just fine, but the next time I connect it to the PC the folder is empty again, although the files are copied into the /sdcard folder and they are still there (I see them on my phones Explorer). One thing to mention is, that I cannot copy folders onto the device which are already there (tried to copy "Music" folder and got an error). The error message then is: "Cannot copy Music\n The device has either stopped responding or has been disconnected".
Does anyone have the same problem?

Did you check whether ADB debugging has been turned off before using MTP?

It was on, but now it is off and I still have the same problem. I did not know, that such a thing happens when USB debug is turned on. Why should it?

For me it works fine with the 24.04.2013 build from CM website. :-s Just flashed it and works perfect, try flashing the latest CM.

that was the problem of first nightlies. swapping two memory storage and in the case u didnt have sd memory card, ur internal memory would be empty. updating to latest nighly will solve it.

I am never able to connect my phone via USB after upgrading to CM. So I use wifi file browser and transfer files.

[Q] Connecting to PC

I have two questions concerning making a connection to a PC and hope someone can help me out here.
After much experimenting, I was finally able to connect my I9000 to my PC, without using KIES. But it was short-lived.
I read about someone removing his micro SD card, making some changes to a setting and then connecting as Storage. Well that worked for me. Once.
Now I can't connect again (Win XP) either with the card inside or without it.
If someone can tell me how to have my PC recognize my I9000 that would be great.
My second question is concerning where files are stored on the I9000.
When I made my only connection, I couldn't see which folder I should be transferring my data files to.
For example my .xls files, or my .doc files, or my .txt files etc etc.?
There are many possible places to copy them to and I'm sure they need to be in the right folder.
TIA
I installed the latest Kies and from it's menu I selected "Driver Recovery" - this installs the latest drivers for your phone.
Then from the home screen select Settings - About Phone - USB Settings - Samsung Kies. Go back to the home screen and plug in your phone - you should be good to go.
You don't have to use the Kies program - the drivers the program installs will show your built-in phone storage and your sd card storage as two seperate volumes in Windows Explorer.
You can also use Window Media Player to sync your music etc.
Note - for the connection to work you have to be using the default TouchWiz launcher on your phone - if you're using LauncherPro or ADW Launcher you'll have to switch back to the TWLauncher - you can use Home Switcher from the market to do this easily.

I'm having a ***** of a time making a connection!
I gave in and installed KIES (said 160MB). It turned out to be over 2G and took over 30 minutes to install!!!
After all that it wouldn't recognize my phone!
I re-imaged my hard drive to get rid of the damn program because un-installing it sure didn't work.
So I'm back to square one. Any other ideas where I can get the necessary drivers for Win XP SP2 ?
TIA
Thats odd - I downloaded Kies and it is only 141mb - I have it in front of me... and while I don't use it for anything it seems to provide the latest drivers. If you look at one of the stickies there is a download for just the drivers... good luck.

Thanks I'll try to find the sticky for the download.
The actual download was 145 MB, but after it finished installing, (which involved an online install) it was more than 2G (I chose the complete install).
Running uninstall got rid of most of the program but not my disk space!
I couldn't find where the files were hiding and certainly wasn't going to mess inside my registry to get rid of stuff.
I tried downloading the drivers but that didn't help.
One of a multitude of problems:
I have my phone connected to PC now (PC doesn't know about phone though)
and I'm in debug mode for USB.
I try to open the App "My Files" and get this friggin' message:
"Your phone does not have a SD card inserted" !!!!
In other words in this state, it is telling me that it can't even recognize the internal SD card!
I've gotten other confusing messages like this one when I've had my 8G external SD card inserted into phone, I launch the App "My Files" and phone tells me there is no SD card inserted!!!
Frustrating!!
A fresh test.
First I insert my 8G micro SD card into my I9000.
Then I go into App "My Files" and I can only see the files on my newly inserted 8G micro SD card. I can't see the files on my internal 8G! (But I could see them using this app just before I inserted my micro card!!!)
Yes, both the internal and the external SD mem are mounted!
Next test. I connect my I9000 to my netbook (Win XP)
and of course my I9000 still isn't recognized by my netbook (it did just once a few days ago).
Then I go into App "My Files" and guess what I get this time?
"Your phone does not have an SD card inserted" !!!
Yeah, tell me about it dear.

Yeah, I know!
Talk about bloat! What does Kies actually do that requires that size?
I think Samsung must be taking the mickey!
They probably think their customers are total idiots...

Maybe I misunderstand. Are you trying to connect to the PC in order to transfer some files to/from PC?
If so, put phone into 'Mass Storage Mode' (from 'Idle screen' > settings >About phone> USB settings> select mass storage.
Connect the usb cable, then pull down from top of screen and confirm to connect as mass storage.
Appologies if you already knew that

Thanks for trying to help. Yes I already knew that, and have done it many times.
I can't help you but I have the same issue in XP SP3
Find 2 removable storage devices (Internal, SD External) but doesn't allow me to browse through either.
It makes sense not giving you access to the internal if the file system is not supported from windows but my sd external is fat32 so it should work.
Unfortunately you can't specify to only use one storage device through external usb connection.
I'd be good to know a workaround for this. I connect my phones to my headunit and it only takes fat32
I had the same experience. I was using AWD Launcher while I was trying to connect to my PC, SGS shows changing, but PC doesn't show anything. As soon as I changed to Samsung Launcher, PC detect my SGS.
so you're telling me that I need to install drivers? it won't be automatic external storage detection just like on a windows mobile device or even the newer iphone 3g onward?

Interesting take on this ado.
At one point I was able to see 2 removable storage devices (Internal, SD External) on my desktop and netbook (both have Win XP SP2).
But, as happened to you, I couldn't get access to them when I clicked on them.
More info that might help with this puzzle:
I installed KIES (full install) and couldn't connect after selecting KIES on the phone).
I am not able to connect using Mass Storage mode either.
I was able to connect ONE time on the netbook and get into the phone folders. I believe this was after installing Samsung New PC Studio 3.
But after that, no dice.
When I first started trying to connect on the desktop and netbook I would get the typical Windows USB connection messages: unknown USB device, would you like to install drivers from this location? etc. etc.
That was good! It showed promise.
Then after a few times I stopped getting those messages from both devices. During that period, I made a partial connection on each device.
I could see two new drives (internal and external SD). But when I clicked on them it showed no space available. Braindead basically.
Something possibly related that I can't figure out at all.
When I go into 'My Files' /sdcard/ will only show SD internal IF my external SD card is not inside the phone. If my SD external card is inside the phone then it shows the SD external only, not the SD internal! Why?
Also very confusing: When I pull down the menu from the top on home screen and select Ongoing: USB connected: Select to copy files to/from computer, then it asks to Mount.
I choose Mount, go to 'My Files' and it says "Your phone does not have an SD card inside!" WTF? (It says that with or without an external SD card inside).
Also strange, when I chose Mount, it then starts to sever the USB connection with messages scrolling by at the top.
So to summarize (this is strictly from the phone's side)
when I connect via Mass Storage it seems to indicate that a USB connection is made. But when I select Mount, the USB connection is terminated!
Success, finally!
I wish I could tell you exactly what the magic bullet was, but it happened gradually. You know how you change something and it seems to help a little. So you change something else and it seems to be getting better?
Here are they key steps that I can remember:
-I went back and re-installed SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe.
There are no messages given after the install completes, they're just drivers, not a program.
-I put the I9000 into debug mode for USB connections (not sure if I need this now).
-After connecting the phone to WinXP I went to phone's home screen, notification window and selected the USB connection and chose to Mount the drive(s).
I can now see and access both the internal SD and the external SD! WOW!
if you want Kies just to manage and organize your phone, i found a better software for that than kies
check here http://forum.xda-developers.com/showthread.php?t=765081
So a driver instal is required. Bugger. I need my external storage to show up and be defaulted to first because it would be nice if I could connect to my headunit in car to get to my mp3's.
Maybe some sort of hack could help here

@ado_civon: I'm not sure you do need to install the drivers.
My issue was that I was not getting the 'USB connected, touch to transfer files' status bar option.
I'm using Dark's ROM (based on Froyo) and don't see the Settings > About Phone > USB settings option. However, when I switched on Settings > Applications > Development > Enable USB debugging, and reconnected, I did get the status bar option.
Sadly, selecting this still did not let my computer (a Win XP machine at work, so I have no administrator rights) recognise the drive. Maybe it works for others, though. On my HTC Hero this works fine, so I'm still not sure why it won't work with the SGS

It will not see the internal SD

Hope someone can help me. Today I just flashed the Rock Rom, and once I am done, I connect the USB cable to my desktop. This is what I usually do with the stock ROM, on the phone I slide the menu bar and click on USB Connect..etc. Once I click it, my explorer will pop up with L: M: directories. One is my ext MicroSD and one is frome the phone, I can see that internal SD folder.
But with this Rock Rom, once I connect to the USB, It saids MTP Connected (what does that mean)? And on my explorer, all I see is the N7000 icon. Inside that it has phone and card folder. But look through both of them, I still can't find my internal sd built in to the phone.
With Stock ROM I got no problem with that. It will say "USB connected" Select to copy files to/from your computer.
If I tab that , I can click on "connect to USB Storage:.
Is there something I need to enable ? How do I change it ?
Really hope some expert can assist me.
Found the problem. For some reason the debug mode is checked.

Internal Memory and Memory Card not showing up on the computer

Hello guys,
I had CM7 running for a while because of its stability. However, I have used CM9 as well for a long time on my P990. Today, I was planning to revert back to CM9 and connected the phone to the computer but the internal memory nor the memory card shows up in my computer. I tried two different laptops and also reflashed cm7 which was already present in my memory card. Still no luck.
When I connect the phone, I get the bell, alert or whatever you want to call it from windows that it has detected that a usb device has connected. Though nothing shows up in my computer. USB Debugging is switched on. And I also press the notification on the phone which should allow me to transfer files between phone and computer.
Im out of ideas, please help.
Re-install the LG USB drivers, found here in the developers section.
I had the same problem when I flashed my phone and everytime I changed roms, I would have to install the drivers again.

And if reinstalling the drivers does not help for whatever reason, and if all that you're trying to do is to push the CM9 rom files from your PC to the SD on your phone, then try following the tip from XDA-TV using SSHDroid. It worked well for me.
http://youtu.be/UI70UYug_zQ
The example in the video is with a Ubuntu machine, but you can follow the same steps for using PC with Putty and WinSCP.
And I haven't tried this, but another alternative is using adbwireless available through Play:

[Q ]CM9 USB connection to Windows 7 64bit failed?

Used to have Xron-mod CM7 on touchpad. This weekend I installed CM9 using novacom and changed the setting to MTP (diabled debugging mode). After plug in usb cable, Windows 7 says it successfully installed cm-tenderloin and recognizes SD storage. CM9 says charging. But when I click SD card under cm-tenderloin, there's nothing. When I tried to builder a new folder, it says NO. Is it a common problem for you guys? If I cannot transfer files between windows and CM9, that will be painful. Thank you for your help. Any clue?

Go to Settings/Storage/ and at the top right click the 3 buttons/USB Computer Connection and select Media device(MTP)
Moved to Q&A
You need to unlock the device before anything will show up under cm-tenderloin.

[Q] MTP access of the SDcard (extern)

Hi
Would like to know if, when you try to access your data stored on the external SD via MTP, you can see all of your files ?
(Using Windows)
This MTP thing is a real mess for me, I can never have the full access to my files. With the Razr i I only have 2 folders with some media files when I open the device with Windows explorer... there should be a plenty of folders and I don't know why I don't see them and how I can see them!
Tks
PS: even with the internat storage I don't have full access. for example, if I create a zip file with some file explorer on the phone, it never show on the MTP device!
Give me back UMS !
That's normal, MTP is a very special mode, so you can't modify files or see some files..
But I don't understand why there isn't an usb mass storage when the phone is connect ?

I would love to have the answer
@ this time: no UMS on the Razr i ...
Then use PTP, it maps /sdcard and /external1 to your computer, you can clearly access them via a normal file manager.
PTP is worst ... it's made only for pictures!
There is no USB Massstorage from 4.0 upwards cause google decided to remove this feature....
ptp is made for pictures but it also can be used for normal files but mtp is prefered....
i am on ubuntu and after a nice little tutorial i am mounting my phone via mtp and i can modify and see everything, its mounted as usb would...
havent tried to see the external card because its ext4 formatted and running arch linux so

I know Google decided to remove ums on the stock Android. But it's not on obligation and constructor have all right to put it if they want.
BTW, I saw same screenshot of a razr vd or a razr maxx which has ums!
I'm running Windows and use Total Commander. There is a great plugin "totalanddroid" that gives me access to all my files (SDcard and internal memory). It uses adb and runs with USB connection or Wifi connection. I tried to find some adb explorer that runs without Total Commander, but none of them is really working on my machine. But maybe you'll have a bit more luck (my phone is not yet rooted, sometimes this seems to be a prerequisite).
NICE

thanks mate, never knew about this plugin. very nice!
Thanks for the workaround.
I'll use this until we have anoher solution as UMS support throught custom rom.
